plying mechanism through the arm 26. This operating means comprises abar or operating shaft 28 which has one end thereof disl posed at anangleto the main body portion to form a short arni29 adapted to belConnecte'd with a pull-rod 30 connected witha brake applying means suchas a foot or hand lever (not shown)y for applying the brake ao- The axle12 isprovided with .a projection 3l adapted to support a bracket 32having a hub 33 andarms 34 extending therefrom for a purpose tobehereinafter described. The

' bracket heretofore described it secured to the projection 3l on theaxle 12 by means of the bolt 35. 'I' 'Ihe free ends of the arms 34 haveopenings therein,adaptedY to receive the pivot pin 36, theV longitudinalaxis of which extends substantially parallelto the longitudinal axisofthe axle l2. The operating bar or shaft 28 isproVided with a pairofarms 37 and 38 exjteilding substantially perpendicular` toy thelongitudinal axis thereof which have openings therein to receive thepivot pin 36 so that the bar 28 is hingedly supportedfthereby. "I heouter end of the bar 28-preferably terminates in a spherically shapedportion 39 :which contacts with the fiat surface 27 of the Aarm^26esubstantially on the axis off'the steering knuckle king pin 11.AY

' Upon movement of the link 30 in the direction ofthe arrow asrshowninFigure 2, it will be seen Ythat the bar 28 which is 'hingedlysupported by thearms 37 and 38 on the ,pin '36 will be moved bodily on aradius about Vthe pin 36 'whereby'the' ball end 39VV on .the bar28 movesin a circular path, and in so doing exerts a pressure against the arm26which l Arotates the shaft 23 supported in the backing fplate 17 t0operate the arm `24 and the connectinglink mechanism comprisingtheplate22 and links 2Q and 2li-to thereby move the brake element-,18 into`engagement with the 'brake Vdrum v16. The VContact point of the ball end39 with the 4fiat, face 27 of the arm`26 is substantiallyon the" axis ofthe king pin 1l and as a result the ball 39 will 'not inadvertentlycause any movement of the arm 26 when the heel l is pivoted during thesteering ofthe -A p vehicle.

Ait 'Wiii be naad yum when the arm-291s *moved in a? clockwise directionasvi'ewed in Figure 2 that the bar 28;will .be swungbodily aboutthepin36 as an axis whereby'the-ball 'en-d 39V will rock the arm` 26, and theshaftV 23 for actuating the brake applying means in thel mannerheretoforeV described. It will 3 also I YV-be understood that the barf28does not in itself have arotatable movementbut that the'. same isadapted to'swingbodily on its pivot for the purpose heretofore'described. While I have shown apreferred movement '-'ofmypresentinvention,V it is tofbe under-- T `-stood, 'however,that formalA changesmaybe lerate .saidbraking means. 5.*In a vehicle, the combination withvan made in the specificembodiment thereof without departing` fromV thespirit and substance of the broad invention the scope of which iscommensurate with the appended claims.

Vhat I claimh is 1. In combination with a vehicle brake, actuating meanstherefor comprising a member hingedly supported intermediate its ends,the-axis'of said support beingoffsetfrom the longitudinal axis of saidmember, and means for swingingsaid member on said support vwhereby thefree end of said member is rotated in a circular path to actuate saidbrake.

2. In combinationfwith a vehicle brake, ac-

tuating means therefor` comprising a bar hiiigedly supported on a memberhaving its longitudinal axis offset from the longitudinal axis-of saidbar,'and means for swinging said baron said support whereby the free endof said bar is rotated in a circular path to ac- 'tuate said brake..

f 3. In combination with'a vehicle brake, ac-

tuating means therefor comprising a stationary member, a member hingedlysupported thereby havingits longitudinal axis at an erating said brakeactuating means comprising, an operating bar extending substantiallyparallel with said axle,A a Vsupport on said axle having itslongitudinalaxis at an anglev to the longitudinal axisy of saidoperating bar hingedly supportingsaid'bar, and means for swinging saidbar on said support for moving the free end thereofin a circular path tooplll.)
